You're only 22....you're not getting married are you? You've got the rest of your life to sleep with other women. You should make the most of a good thing while it last otherwise you'll regret it, it sounds like you've got a good thing with this girl so don't ruin it for a shag. Save the shagging around for after your relationship has run it's course, that way you'll enhoy it more instead of questioning if it was worth the sacrifice. If you're quesitoning it now you'll either still be questioning or regretting after.
Now, see that is some good womanly advice. All you have to do is the exact opposite.
If you stay with this girl, knowing what you know. It will eat at you because you are insecure about it. A woman does not give you confidence. Accomplishing goals and living the life you want gives you confidence. If getting a "girlfriend" was a goal and you achieved it, then that achievement gave you confidence, but HER as a person did not. If you can get one girlfriend you can get another. You know that now.
Never ask about a woman's past. You really don't want to know and at best you may force her to lie, at worst you force her to tell you the truth. Neither will satisfy the man insecure enough to even ask.
Now that you know, its going to take probably more than you have to get it out of your head. So listening to this person's advice is not going to help you. Oh parts of it is brilliant. You are 22 and you do have the rest of your life, and if you are not getting married....(that's where the good parts end)...if you're not getting married, go and play the field. If you have these sorts of doubts and fears the relationship is already on it's way to being over. The poison as been poured into the well. There are more women out there and there are other good relationships to be had while you are young. Go and enjoy yourself, you are too young to live with these sorts of crippling self doubts and insecurities. This is about you and your life, not about her and her sex life. This is about you finding out about yourself as a man.
Go forth young man and see what's out there. Be not afraid nor apologetic for what you want. A man goes and gets what he wants. You want more? Go get it. Nobody is going to get it for you, and no one is going to coddle you and tell you it's all good. It's your choice. Always remember that...you have a choice and the life you lead stems directly from the choices you make. If you are miserable and do nothing about it, there is no one to blame but yourself. Good luck.
